Description

  The present invention relates to a garbage disposal apparatus for treating garbage discarded from homes, restaurants, hospitals, schools, food factories, and the like.

  So-called food waste from homes and restaurants includes organic substances such as starch, proteins, oils and fats, and fibers (for example, cellulose) derived from cooking scraps and leftovers of various foods. Of the waste that is separated as combustible waste, especially garbage is rich in moisture. For this reason, the amount of energy required to incinerate garbage increases.

Moreover, the moisture of garbage lowers the combustion temperature and induces the generation of dioxins. For this reason, environmental pollution by dioxins generated from waste incineration facilities is a problem. In addition, there are problems such as a shortage of final landfill site for incineration waste and dioxin spillage from landfill.
Therefore, there is an increasing interest in techniques for reducing the amount of dry waste, decomposing it using microorganisms, and crushing it without incineration.

  For example, a disposer that pulverizes raw garbage, adds water to it, and discharges the pulverized raw garbage as a slurry-like fluid into a drain pipe, so there is almost no need for each individual to take out the processed garbage. , Has been especially noted. In general, the disposer is a continuous type in which the disperser is activated and then continuously poured and pulverized, or the batch type in which the culm is stored in advance in the disposer and pulverized in a single operation. There is a thing.

  In any of the above-described disposers, it is necessary to flow water through the disposer during or before the operation of the disposer in order to prevent the drainage pipe from being clogged with the slurry-like fluid.

  The flow rate of water varies depending on the size of the disposer and the operation method, but a flow rate of about 6 to 10 liters / min is required to properly operate the disposer. Therefore, it has been proposed to automatically supply a sufficient amount of water so that the crushed garbage has sufficient fluidity to prevent clogging of the garbage after pulverization (Patent Document). 1). It has also been proposed to prevent clogged raw garbage from being clogged by supplying a cleaning medium to the pipe (see Patent Document 2).

On the other hand, a technique for decomposing garbage by the action of an oxidizing agent such as ozone or hypochlorous acid has been proposed. For example, there has been proposed a method for deodorizing the solid content of garbage separated into solid and liquid by ozone gas and decomposing part of organic substances contained in the separated liquid (see Patent Document 3). In addition, a method has also been proposed in which reducing substances such as garbage are electrolyzed in the presence of water and halides at 100 ° C. or lower and then heated to 100 ° C. or higher to perform further electrolysis. (See Patent Document 4).

However, the techniques described in Patent Documents 1 and 2 have the following problems when it is difficult to crush the garbage itself.
For example, (1) raw fish skin, bird skin, squid skin, melon and watermelon skin, corn and bamboo shoot skin, green soybean pods, corn and cabbage cores, raw pumpkins and radishes Large lumps and cores of quality and vegetables are difficult to crush. For this reason, it is necessary to divide these into several times, or to divide a large chunk into smaller chunks. Therefore, these processes are troublesome.
(2) Also, it takes time to treat takuwan, chicken, fish bone, eggplant and pepper, etc., sardines, raw rice cakes, grape branches, and onion skin.

  In the technique described in Patent Document 3, ozone, which is an oxidizing agent, is used not for decomposing solids but for decomposing part of organic substances contained in volatile odorous substances and separated liquids. Yes. Therefore, it is necessary to discharge the solid content separately. In Patent Document 3, since the solid content remains large, if the solid content is allowed to flow as it is, a problem such as clogging of piping occurs.

  The technique described in Patent Document 4 is intended to completely decompose organic matter in garbage into carbon dioxide and the like by the action of electrolysis. Enormous energy is required for complete decomposition of organic matter. Furthermore, in Patent Document 4, since the electrolysis is performed at a high temperature in the presence of an organic substance, the deterioration of the electrode proceeds and the running cost increases. On the other hand, when the sewer and the biological treatment tank are arranged in the subsequent stage, it is not necessary to completely decompose the organic matter.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a garbage disposal apparatus that makes it possible to reduce the size of garbage efficiently by a simple operation and to prevent clogging of garbage from a transportation pipe or the like.

The present invention relates to a garbage disposal apparatus further comprising pH measuring means for measuring the pH of the oxidizing agent and pH control means for adjusting the pH of the oxidizing agent .
In the present invention, garbage refers to leftovers, cooking scraps, etc. generated in ordinary households, restaurants, and canteens. For example, raw garbage includes vegetables, fruits, meat, fish, grains, beverages, and the like. Such garbage contains polysaccharides such as starch and cellulose, proteins such as albumin and keratin, lipids, amino acids, saccharides, organic acids, and fatty acid salts as nutritional components. In such garbage, generally, organic matter accounts for about 97%, and inorganic materials such as salt account for the remaining 3%.
Further, in the present invention, the accommodation refers to a mixture containing the above garbage and an oxidizing agent.

  In the above garbage disposal apparatus, the treatment tank preferably includes a discharge port for discharging the contents before and after crushing.

  It is preferable that the garbage processing apparatus further includes (6) a crushing tank for storing the contents discharged from the processing tank, and the crushing means is provided inside the crushing tank.

  In the above garbage disposal apparatus, the crushing tank preferably includes a discharge port for discharging the crushed contents.

  It is preferable that the garbage processing apparatus further includes a temperature measuring unit that measures the temperature of the contents in the processing tank, and a heating control unit that controls the heating unit using information obtained by the temperature measuring unit.

  The garbage processing apparatus has an electrolyzed water generating unit in which an oxidizing agent supplying unit electrolyzes water containing an electrolyte to generate electrolyzed water, and the electrolyzed water generating unit is an electrolytic cell for storing water containing an electrolyte, electrolysis It is preferable to include an anode and a cathode disposed in the tank, and an energization device for energizing between the anode and the cathode.

  In the above garbage disposal apparatus, the electrolyte preferably contains at least one selected from the group consisting of sodium chloride, calcium chloride, potassium chloride, sodium bromide, calcium bromide, and potassium bromide.

Before Symbol p H control means, and this is preferably a means for adjusting the pH of the oxidant at the cathode water produced near the cathode of the electrolytic water generating unit.

  It is preferable that the garbage processing apparatus further includes a weight measuring unit that detects the weight of the processing tank.

  Preferably, the garbage disposal apparatus further includes an open / close detection unit that detects an open / closed state of the lid, and the heating control unit controls the heating unit using information from the open / close detection unit.

By the garbage processing apparatus of this invention, it heats with an oxidizing agent, a garbage is softened, and the garbage after the heating is crushed. Thereby, while the particle size of garbage becomes smaller, the affinity to water improves. Moreover, even if garbage is a high molecular weight thing, it will be easily hydrolyzed by the heated water by the affinity to water improving by the oxidizing action of an oxidizing agent. For this reason, it becomes easy to dissolve or disperse food waste in water. In addition, since the treated garbage is highly dispersible in water, even when the garbage is discharged together with water, it is difficult for sediment to accumulate and the resulting pipe clogging.
Furthermore, by using the garbage processing apparatus of the present invention, it is possible to easily crush even garbage that has been difficult to crush conventionally. For this reason, it is possible to save the trouble of throwing away garbage into several batches or dividing a large chunk into smaller chunks.
The garbage disposal apparatus of the present invention is further provided with a pH measuring means for measuring the pH of the oxidizing agent and a pH control means for adjusting the pH of the oxidizing agent, so that the oxidizing effect by the oxidizing agent is increased. it can.

  First, the garbage processing apparatus of this invention is demonstrated. The garbage processing apparatus of the present invention has an input port for garbage, a treatment tank for containing garbage and an oxidant, an oxidant supply means for supplying an oxidant to the treatment tank, and a garbage provided in the treatment tank. At least a lid for closing the inlet, a heating means for heating the contents of the treatment tank, and a crushing means for crushing the garbage.

  A processing tank accommodates garbage and an oxidizing agent. In the treatment tank, the garbage is heated together with the oxidizing agent, and the garbage is softened.

In the treatment tank, the garbage is heated together with the oxidizing agent. Therefore, the treatment tank is preferably made of a material that is not easily corroded by the oxidizing agent in a heated state and has sufficient durability against a pressure increase. Examples of such a material include stainless steel (for example, SUS304 and SUS316), heat resistant alloys such as Hastelloy and Inconel, and fluorine resins such as polytetrafluoroethylene (PTFE) and perfluoroalkoxyalkane (PFA). .
In addition, the whole processing tank may be comprised with the above materials. In addition, at least the inner surface of the treatment tank in contact with the garbage and the oxidizing agent may be configured or coated with the material as described above.

  When heating the garbage and the oxidant, it is preferable that the inside of the treatment tank can be a sealed space so that water vapor or gas generated by heating does not escape to the outside. For example, the treatment tank can be sealed by providing the garbage treatment apparatus with a lid that can close the inlet provided in the treatment tank. At this time, when the garbage and the oxidizing agent in the treatment tank are heated particularly at 100 ° C. or higher, the pressure in the treatment tank rises. For this reason, it is preferable that the provided lid has a pressure resistance capable of sealing the treatment tank even in a high pressure state.

  The input port provided in the treatment tank is preferably as large as possible so that lump-like garbage can be input. For this reason, it is preferable that the lid | cover which closes an insertion port is comprised from the pressure | voltage resistant member like the lid | cover of a pressure cooker. For example, the pressure-resistant member includes a lid body made of the same material as that of the treatment tank and a packing or O-ring made of a heat-resistant metal or resin such as a stainless alloy or a fluororesin.

  Furthermore, it is preferable that the treatment tank has a pressure regulating valve for releasing the internal steam. As a result, even when the internal pressure of the processing tank is excessively increased due to abnormal gas generation, it is possible to release the pressure and prevent the processing tank from bursting. That is, the safety can be improved by providing the pressure regulating valve. In addition, it is preferable to set the pressure | voltage resistance of this pressure control valve to a value smaller than the intensity | strength of a processing tank being ensured, for example, several MPa or less.

  The oxidizing agent supply means supplies an oxidizing agent to the processing tank. As an oxidizing agent supply means, what consists of a tank which stores an oxidizing agent and a valve which discharges an oxidizing agent is mentioned, for example.

  The oxidizing agent includes an oxidizing substance. Examples of the oxidizing substance include ozone, hydrogen peroxide, halous acid, hypohalous acid, permanganate ion, chlorine, dichromate ion, oxygen, chlorine dioxide, and hypochlorite ion. Examples of the halogenous acid include chlorous acid, bromic acid, and iodic acid. Examples of hypohalous acid include hypochlorous acid, hypobromous acid, and hypoiodous acid. Further, when the oxidizing agent contains at least one of halogenous acid and hypohalous acid as the oxidizing substance, chlorous acid or bromic acid is preferable as the halogenous acid from the strength of oxidizing power, As the hypohalous acid, hypochlorous acid or hypobromous acid is preferable. In addition, the oxidizing agent may contain only 1 type of the above oxidizing substances, and may contain 2 or more types of oxidizing substances.

  In the present invention, the oxidizing substance as described above may be used as it is as an oxidizing agent, or water containing the oxidizing substance may be used as an oxidizing agent.

  When water containing an oxidizing substance is used as an oxidizing agent, the oxidizing agent is prepared, for example, by dissolving the oxidizing substance in water or diluting a substance containing an oxidizing substance at a high concentration in water. be able to. For example, ozone generated in the air by an ozone generator is added to water, hydrogen peroxide (diluted for ease of storage) or liquid chlorine is added to water, sodium chlorite, hypochlorous acid By adding sodium acid, calcium hypochlorite (including highly bleached powder), potassium permanganate, or potassium dichromate to the water, water containing the oxidizing agent can be made. Alternatively, an aqueous solution obtained by adding hydrochloric acid to sodium chlorite to produce chlorine dioxide and dissolving the chlorine dioxide in water can be used as an oxidizing agent.

  The oxidizing substances as described above include those that are the first class of dangerous substances. Such oxidizing substances must be handled by a person with a license for a dangerous goods handler and must be used with care.

  The oxidant may be supplied into the treatment tank by an oxidant supply means from an inlet provided in the treatment tank. Further, the oxidant supply means and the treatment tank may be connected by a pipe, and the oxidant may be supplied to the treatment tank through the pipe. When the oxidant supply means and the treatment tank are connected by a pipe, the oxidant supply means is, for example, an oxidant so that the pressure in the treatment tank does not leak outside when the oxidant and garbage are heated. It is preferable to provide an opening / closing mechanism that can make the treatment tank a closed space between the supply means and the pipe. As such an opening / closing mechanism, for example, a pressure-resistant manual valve or an electric valve used in a water heater or a chemical plant can be used. The opening / closing mechanism may be provided in the middle of a pipe connecting the oxidant supply means and the processing tank.

  Furthermore, electrolyzed water containing the above oxidizing substances can also be used as the oxidizing agent. The electrolyzed water containing an oxidizing substance can be produced, for example, by electrolyzing water in which an electrolyte that generates an oxidizing substance by electrolysis is dissolved. Since such electrolyzed water contains an oxidizing substance, for example, hypochlorous acid, hydrogen peroxide, etc., without adding the oxidizing substance, it is easy to handle. For this reason, such electrolyzed water is particularly preferable as an oxidizing agent used in the garbage treatment apparatus of the present invention.

  Electrolyzed water containing an oxidizing substance can be produced by electrolyzing only tap water containing residual chlorine. Electrolysis can be carried out smoothly by further dissolving the electrolyte in the water to be electrolyzed. As the electrolyte, for example, a halogen salt, calcium lactate, or calcium glycerophosphate can be used. Among these, it is particularly preferable to use a halogen salt as the electrolyte because the amount of acidic substances in the electrolytic water can be increased.

When water in which a halogen salt is dissolved is electrolyzed, the following formula:
2X ⁻ → X ₂ + 2e ⁻ (1)
X ₂ + H ₂ O → HXO + HX (2)
As shown in FIG. 2, the oxidizing substances chlorine and hypohalous acid are generated in the vicinity of the anode. In the above formulas (1) and (2), X is F, Cl or Br.

  Halogen salts include chloride, bromide, or fluoride. Among these, sodium chloride, potassium chloride, calcium chloride, sodium bromide, potassium bromide and calcium bromide are particularly preferable because they have a high degree of dissociation into ions and are easy to handle.

  In the garbage processing apparatus of the present invention, when electrolyzed water is used as the oxidizing agent, the electrolyzed water may be separately prepared and supplied to the oxidizing agent supply means. Alternatively, the oxidizing agent supply means may include an electrolyzed water generating unit that generates at least electrolyzed water.

  The electrolyzed water generating unit includes, for example, an electrolyzer that contains the electrolyte and water containing chlorine, an anode and a cathode that are disposed in the electrolyzer so that at least a portion thereof is in contact with the accommodated water, and an anode and a cathode And an energization device for energizing between. A diaphragm may or may not be provided between the anode and the cathode.

When using an electrolyzed water generating unit having an electrolytic cell in which a diaphragm is provided between an anode and a cathode, for example, a direct current voltage is applied between two electrode plates in contact with water containing an electrolyte by an energizing device. Thus, electrolyzed water can be obtained. At this time, strong acid anodic water obtained in the vicinity of the anode, strongly basic cathodic water produced on the cathode side, or a mixture of anodic water and cathodic water as appropriate can be used as the oxidizing agent.
For example, when water in which sodium chloride is dissolved is electrolyzed, at least the anode water contains hypochlorous acid.

  Moreover, when using the electrolyzed water generating part provided with an electrolyzer having no diaphragm between the anode and the cathode, the electrolyzed water in the vicinity of the anode and the cathode is mixed, so that weakly acidic electrolyzed water can be obtained. . In addition, by adding an acid etc. to the water containing electrolyte beforehand, even if it uses the electrolyzed water production | generation part in which an electrolytic cell does not have a diaphragm, it becomes possible to obtain strongly acidic electrolyzed water.

  As described above, it is possible to generate, for example, acidic electrolyzed water, weakly acidic electrolyzed water, electrolytic hyponitrous acid, or alkaline water by changing the presence or absence of the diaphragm and the type of electrolyte contained in the water containing the electrolyte. it can.

  The electrolytic cell constituting the electrolyzed water generation unit can be made of, for example, a resin such as vinyl chloride resin, polypropylene, polyethylene, polyethylene terephthalate (PET), ebonite, or a material such as ceramics. Further, for example, an iron tank with a high insulation lining made of rubber, synthetic resin or the like may be used as the electrolytic tank.

  As a material for the electrode, it is preferable to use a material usually used for an electrolysis reaction, for example, a material having ruthenium, iridium, platinum, palladium, rhodium, tin, or an oxide or ferrite thereof on the surface. The electrode itself may be made of the material as described above, or the surface of the electrode substrate may be coated with the material as described above. Moreover, as an electrode material, an alloy containing the above metal element is also preferably used. Examples of such an alloy include a platinum-iridium alloy, a ruthenium-tin alloy, and a ruthenium-titanium alloy. The above metals and alloys are excellent in corrosion resistance, and exhibit excellent insolubility when used as an anode.

  Further, the electrode for generating chlorine is required to have insolubility in electrolyzed water, durability during reverse voltage cleaning, and the like. As such an electrode, an electrode made of palladium, ruthenium, or an alloy of platinum and iridium is particularly preferable.

  The cathode is not required to be strictly insoluble. For this reason, as a cathode, what consists of nickel alloys, such as stainless steel, carbon steel, titanium, or a titanium alloy or Hastelloy, Inconel, can be used, for example.

  Examples of the diaphragm include, for example, an unglazed plate (porous sintered body), a ceramic, a wire net, a perforated metal plate, a glass fiber nonwoven fabric, a hydrophilic polymer membrane (polyester nonwoven fabric), an ion exchange membrane, a polypropylene nonwoven fabric, a polyethylene chloride membrane, A polytetrafluoroethylene film, a vinylidene fluoride film, a polyolefin-based resin film, a Flemion film, or a substitute made of rubber or plastic material can be used. For example, as the diaphragm, a nonwoven fabric made of polyester or glass fiber covered with a hydrophilic resin film having a pore diameter of 0.2 to 200 μm can be used.

  As the energization device, a device generally used in electrolysis can be used without any particular limitation.

  Piping for flowing electrolyzed water to a processing tank etc. can be comprised by the pipe | tube etc. which consist of hard vinyl chloride resin, for example.

The electrolysis is preferably performed at a voltage of 5 to 50 V and a current of 0.5 to 600 A / m ² per electrode surface area. When the current density is larger than 600 A / m ² , the surface of the anode is peeled off or the material constituting the anode is easily eluted. When the current density is smaller than 0.5 A / m ^2, it is necessary to increase the area of the anode, so that it is difficult to reduce the size of the electrolyzed water generation unit.

Moreover, when an oxidizing water supply means is provided with an electrolyzed water production | generation part, it is preferable that the garbage processing apparatus of this invention is equipped with the water supply means for supplying water to the said electrolyzed water production | generation part. This water supply means should just be what can supply the quantity of water required at the time of electrolysis to an electrolyzed water production | generation part. As such a water supply means, it can be comprised from the tank and valve | bulb which hold | maintain the quantity of water more than the quantity used at once in the electrolyzed water production | generation part, for example.
Alternatively, the electrolyzed water supply means may be connected to the water supply via an electromagnetic valve, and water may be supplied to the electrolyzed water supply means by opening the electromagnetic valve.

When the oxidizing agent contains, for example, hypochlorous acid, hypochlorite ions and / or chlorine as an oxidizing substance, the effective chlorine concentration of the oxidizing agent is preferably 50 to 3000 ppm. Among them, the effective chlorine concentration is more preferably 500 to 3000 ppm because the oxidation of garbage proceeds more efficiently. When the effective chlorine concentration is less than 50 ppm, the oxidizing power is insufficient. When the effective chlorine concentration exceeds 3000 ppm, the oxidizing power becomes sufficient, but the corrosion of the portion containing the oxidizing agent and the like increases.
These are the same when the oxidizing agent is electrolyzed water.

  When softening garbage, it is preferable that the oxidizing effect by the oxidizing agent is as large as possible. For example, when the oxidizing agent contains hypochlorous acid as an oxidizing substance, the pH of the oxidizing agent is preferably 3 or more and 6.5 or less. This is because the presence of hypochlorous acid (a form in which protons are not dissociated) having strong oxidizing power compared to hypochlorite ions (a form in which protons are dissociated) is 90% or more.

  In order to adjust the pH of the oxidizing agent within the above range, the garbage treatment apparatus of the present invention includes a pH measuring means for measuring the pH of the oxidizing agent and a pH control means capable of adjusting the pH of the oxidizing agent. It is preferable to further provide. In addition, adjustment of pH of an oxidizing agent may be performed in an oxidizing agent supply means, and may be performed in the state which the oxidizing agent contacted with garbage in the processing tank.

As said pH measurement means, a semiconductor type pH sensor (made by Shindengen Electric Co., Ltd.) is mentioned, for example. The pH control means is not particularly limited as long as the pH of the oxidant in the oxidant supply means or the treatment tank can be adjusted to 3 or more and 6.5 or less. Examples of the pH control means include a tank comprising a pH adjusting agent and a valve for discharging the pH adjusting agent.
Here, examples of the pH adjuster include mineral acids such as hydrochloric acid and sulfuric acid, organic acids such as acetic acid and citric acid, alkalis such as sodium hydroxide, potassium hydroxide and calcium hydroxide, and aqueous solutions thereof. .

  When the amount and the pH of the garbage to be introduced are known in advance, the pH of the oxidizing agent after mixing with the garbage can be adjusted only by adjusting the pH of the oxidizing agent to be added. In this case, it is preferable that the oxidizing water supply means includes a pH measurement means and a pH control means. At this time, the pH of the oxidant in the oxidant supply means is adjusted by the pH control means while the pH is measured by the pH measurement means so that the oxidant after mixing with the garbage has a predetermined pH. .

  In addition, when the pH of the oxidant is adjusted in a state where it is in contact with the garbage in the treatment tank, the pH measuring means is capable of actually measuring the pH of the oxidant in a state of being in contact with the garbage. It is preferable to be provided in the treatment tank. Thereby, it is possible to adjust the pH of the oxidant by the pH control means while confirming that the pH of the oxidant mixed with the garbage falls within the range of 3 to 6.5.

In addition, when an oxidizing agent supply means is provided with the electrolyzed water production | generation part, and acidic anodic water is used as an oxidizing agent, basic cathodic water can be used as a pH adjuster. The use of cathode water as a pH adjuster in this manner is particularly preferable because it is not necessary to provide a tank or the like for storing the pH adjuster.
Moreover, it is also possible to preset the pH of the oxidizing agent within the above range by mixing anode water and cathode water at a predetermined ratio. In this case, since the electrolyzed water generating unit also serves as the pH control unit, it is not necessary to provide the pH control unit again.

Garbage in the treatment tank is heated by the heating means together with the oxidizing agent. As the heating means, means capable of heating the garbage and the oxidant accommodated in the treatment tank can be used without any particular limitation. Examples of the heating means include an electric heating device using Joule heat, a combustion device using combustion heat such as gas or petroleum, a heat pump, an induction heating device, and the like.
When a contact heating device such as an electric heating device is used as the heating means, in order to increase the heating efficiency, the heating means is installed on the inner wall of the processing tank, or a coiled heating means such as a throwing heater is used as the processing tank. It is preferable to directly contact the internal contents.

  In addition, after discharging the treated garbage, the inside of the treatment tank can be sterilized or dried by using an oxidizing agent and a heating means so that germs do not propagate in the treatment tank.

The heating temperature of the container containing the oxidizing agent and the garbage is set to a temperature at which the organic matter constituting the garbage is sufficiently softened or a temperature at which the organic substance constituting the garbage is liquefied by being reduced in molecular weight. In the present invention, the heating temperature is preferably 150 ° C. or less.
When the heating temperature exceeds 150 ° C., the organic matter constituting the garbage is reduced in molecular weight, and the polymerization of the reduced molecular component begins to occur, and a polymer such as tar tends to be generated. For this reason, the softening or low molecular weight of garbage does not progress greatly. When tar is generated, the tar adheres to the inner wall of the treatment tank, resulting in poor maintainability. Moreover, since equipment corresponding to high temperature and high pressure is required, it is not preferable from the viewpoint of safety. Furthermore, if the treatment tank is subject to laws and regulations (Occupational Safety and Health Act boiler and pressure vessel safety regulations), individual inspection is required, making mass production of equipment virtually impossible.

  Therefore, in order to control the heating temperature, the garbage processing apparatus of the present invention controls the heating means by using the temperature measuring means for measuring the temperature of the contents in the treatment tank and the information obtained from the temperature measuring means. It is preferable to include a heating control means. At this time, the heating temperature by the heating means is preferably controlled to 150 ° C. or lower.

It is preferable that the temperature measuring means can measure the temperature of the contents in the processing tank and has pressure resistance during heating and chemical durability. As the temperature measuring means, for example, a thermocouple whose surface is covered with stainless steel, a thermocouple made of a chromel-alumel alloy, and a thermocouple made of a platinum alloy can be used. Moreover, in order to improve heat insulation and to reduce the energy loss at the time of heating, it is preferable that the surface of the thermocouple is covered with a heat insulating material such as glass wool.
As the heating control means, for example, a digital temperature controller including a thermostat, a microcomputer, or the like, or a device in which a temperature sensor and a relay are combined can be used.

In addition, in order to control the heating unit so that it cannot be operated unless the lid that closes the charging port provided in the processing tank is closed, an open / close detection unit that detects the open / closed state of the charging port lid is provided. Is preferred. This open / close detection means is connected to the heating control means. Examples of the open / close detection means include a switch that operates according to the load on the lid, a load sensor, a pressure sensor, an infrared sensor, and an optical sensor.
By providing such an open / close detection means and controlling the operation of the heating means, the chance of human contact with the heated garbage and oxidant, and the water vapor and gas generated by heating is reduced, and safety is improved. It becomes possible to improve. Moreover, when heating garbage and an oxidizing agent especially at 100 degreeC or more, it can prevent that water and an oxidizing agent evaporate and a processing tank will be in an empty state. Furthermore, by controlling the heating means to be operated while the lid is closed, the trouble of manually operating the heating means can be saved.

In order to effectively promote the softening or low molecular weight of garbage at low temperatures, especially at temperatures below 100 ° C., the affinity of hydrophobic organic substances to water is ensured by allowing the oxidizing agent to sufficiently act on the garbage. Need to be increased. Therefore, when heating garbage at a heating temperature of 50 ° C. or more and less than 100 ° C., it is preferable to use an oxidant whose effective chlorine concentration is adjusted to 500 ppm or more and pH 3 or more to 6.5 or less. Further, at this time, it is preferable to add the oxidizing agent so that the ratio of the garbage to the total weight of the oxidizing agent and the garbage (hereinafter also referred to as the weight ratio of the garbage) is 60% or less.
By heating the garbage under the above conditions, for example, when the oxidizing agent contains hypochlorous acid as an oxidizing substance, a sufficient amount of hypochlorous acid is particularly effective against the organic matter in the garbage. It acts in a strong form (a form in which protons are not dissociated). For this reason, even if the garbage contains a high molecular weight organic substance such as cellulose having a strong hydrophobic property, the affinity to water is improved, and the garbage is denatured to be easily hydrolyzed. As a result, even in a temperature range of 50 ° C. or more and less than 100 ° C., where the rate of hydrolysis of food waste has been slow, the food waste is hydrolyzed and the food waste can be softened within a few hours.

  Further, by setting the heating temperature to less than 100 ° C., the required specifications for heat resistance and pressure resistance of the treatment tank are greatly relaxed. For this reason, it becomes possible to comprise a garbage disposal apparatus at low cost.

  As described above, it is necessary to measure the input weight of the garbage itself and the input weight of the oxidizing agent in order to input the oxidizing agent to the treatment tank so that the weight ratio of the raw garbage becomes 60% or less. . Therefore, it is preferable that the garbage processing apparatus of this invention is equipped with the weight measurement means which measures the weight of a processing tank. An example of the weight measuring means is a load cell.

When the oxidizing agent is introduced into the treatment tank so that the weight ratio of the garbage is 60% or less, the weight measuring means can be used as follows.
For example, first, the user measures the weight of the thrown-in garbage (the difference between the weight of the treatment tank after throwing in the garbage and the weight of the treatment tank in an empty state) using the weight measuring means. Thereafter, the oxidizing agent is fed into the treatment tank by the oxidizing agent supply means. When the weight ratio of the garbage becomes 60%, for example, the introduction of the oxidizing agent is stopped.
Note that the weight of the garbage may be measured by the weight measuring means after detecting that the lid of the inlet of the processing tank is closed by the open / close detecting means.

The softened garbage contained in the storage after heating is crushed by the crushing means. Thereby, the particle size of garbage is further reduced.
Examples of the crushing means include a mill such as a cutter mill and a chain mill, a mixer having rotary blades or rotary blades such as a Henschel mixer, and a medium such as metal particles, resin particles or glass particles, Examples include ball mills and shakers that give rotation and grind garbage. In addition, the shape and size of the rotary blade and the rotary blade, the number of rotations, and the rotation time are appropriately changed depending on the type and amount of garbage.

  In the garbage processing apparatus of the present invention, the crushing means can be installed inside the processing tank, for example.

  Prior to heating the garbage with the heating means, the crushing means can be operated to perform rough crushing of the garbage. This rough crushing step makes it possible to soften the garbage in a shorter time.

  Moreover, it is preferable that the garbage processing apparatus of this invention is equipped with a crushing tank separately from a processing tank, and a crushing means is arrange | positioned at the crushing tank. In this case, the garbage is heated in the treatment tank, and the softened garbage is crushed in the crushing tank.

  By providing a crushing tank separately from the treatment tank, it is possible to prevent the crushing means from being heated. For this reason, it is not necessary to achieve both heat resistance and chemical durability for the material constituting the crushing means, and the initial cost can be reduced. Furthermore, deterioration due to heat shock of the crushing means can be suppressed.

  As a material constituting the crushing tank, in addition to the same material as that constituting the treatment tank, for example, polyethylene and polypropylene having excellent chemical durability, although heat resistance is inferior to the above-mentioned material constituting the treatment tank. A resin such as a hard vinyl chloride resin can be used.

  For example, the discharged contents from the processing tank to the crushing tank can be discharged using a discharge valve installed between the processing tank and the crushing tank. When the garbage is heated in the treatment tank, the discharge valve is closed. After the heating in the treatment tank is completed, by opening the discharge valve, the contents containing the softened garbage can be discharged into the crushing tank. In addition, opening and closing of the discharge valve may be performed manually, or may be performed automatically after the heating in the treatment tank is finished.

Moreover, in the garbage processing apparatus of this invention, when the crushing tank is provided in the processing tank, it is preferable to provide a discharge port in the crushing tank. With this discharge port, the crushed contents can be discharged to the outside without turning over the garbage disposal device. Here, it is preferable that the discharge port provided in the treatment tank or the crushing tank can withstand the internal pressure of the treatment tank during heating and can be opened and closed. The opening and closing of the discharge port may be performed manually or automatically after the garbage is crushed.
Further, this discharge port may be directly connected to an external drain pipe including a sewage pipe.
It should be noted that the crushed contents may be taken out from the garbage input provided in the treatment tank by turning over the garbage processing apparatus.

  For example, when discharging the crushed contents from the outlet to an external drain pipe, a pressure-resistant manual valve or a pressure-resistant manual valve for communicating the inside and outside of the treatment tank so that the crushed contents are easily discharged. It is preferable to provide an electric valve in the treatment tank. Even when a large amount of liquid is introduced into the processing tank, the pressure-resistant manual valve or motor-operated valve is preferably arranged in the upper part of the processing tank in order to ensure communication with the outside.

  Moreover, when a garbage processing apparatus is further provided with the crushing tank, what is necessary is just to provide the manual valve or an electric valve in either a processing tank or a crushing tank. In addition, when a manual valve or a motor operated valve is provided in the processing tank, it is necessary to open an external discharge valve provided between the processing tank and the crushing tank.

  Moreover, after making the inside of the treatment tank communicate with the outside by opening the input port, the crushed contents may be discharged from the discharge port.

  Furthermore, it is preferable that the bottom part inside a processing tank and a crushing tank incline so that it may become low toward a discharge port. As a result, the crushed contents can easily flow into the discharge port provided in the processing tank or the crushing tank.

Further, when an external drain pipe is connected to the drain of the treatment tank or the crushing tank, for example, it is preferable to arrange a classification means between the drain and the external drain pipe. As this classifying means, any means capable of allowing garbage having a predetermined particle diameter or less to pass through can be used without any particular limitation.
By arranging such classification means, it is possible to prevent garbage that is not sufficiently pulverized from clogging the external drainage pipe and block the external drainage pipe. Moreover, you may provide a classification means in the lower part of a processing tank or a crushing tank.
In addition, the garbage which could not pass the classification means is processed again when the next garbage is thrown in, and is gradually refined.

As the classifying means, for example, a mesh member such as a filter or a net, or a plate member having a through hole can be used. As a material constituting the classification means, the same material as that of the treatment tank can be used.
When the classification means is disposed between the discharge port of the crushing tank and the external drain pipe, the crushing tank is not heated. For this reason, as a material constituting the classifying means, for example, a resin having high chemical durability but not high heat resistance such as polyethylene and polypropylene can be used.

  The crushed contents are, for example, a treatment tank or crush by providing a mechanism (trap) for storing a certain amount of water in the treatment tank and discharging the water exceeding the certain amount in the external drain pipe. It can be discharged from the tank.

  In addition, an external discharge valve is provided between the classification means and the external drain pipe, and after detecting the end of crushing by the crushing means, the external discharge valve is opened to discharge the contents in the processing tank or crushing tank. Also good. The opening of the external discharge valve may be performed manually, or may be automatically performed using a detection unit that detects the end of crushing.

  As the detection means for detecting the end of crushing, a sensor for detecting the rotation speed or the number of rotations can be used if the crushing means is a rotary type by a motor, for example. Alternatively, after counting a predetermined time from the start of crushing, the crushing means may be automatically stopped and the external discharge valve may be opened.

  As mentioned above, it is preferable to treat garbage with an acidic oxidizing agent. In this case, the heated contents are often strongly acidic. Therefore, it is preferable to neutralize the crushed contents before discharging them from the processing tank or before discharging the heated contents from the processing tank to the crushing tank. Therefore, it is preferable that the garbage processing apparatus of this invention is equipped with the neutralization means which can neutralize the thing of a processing tank near neutrality.

When the garbage processing apparatus includes both the treatment tank and the crushing tank, it is also conceivable to neutralize the contents in the crushing tank. However, in order to suppress deterioration of the crushing tank and the crushing means, it is preferable to neutralize the heated contents in advance in the treatment tank and discharge the neutralized contents to the crushing tank.
It should be noted that the crushed container may be neutralized for another place.

  As a neutralization means, what can neutralize the thing after crushing or after heating to neutral vicinity can be used without being specifically limited. For example, as a neutralization means, the apparatus which consists of the tank which accommodates a neutralizing agent and the valve which controls supply of the neutralizing agent is mentioned, for example. Here, as the neutralizing agent, for example, sodium thiosulfate, caustic soda, aqueous ammonia, or slaked lime can be used.

  In addition, when the garbage processing apparatus of the present invention includes an electrolyzed water generation unit that can separate and take out the anode water and the cathode water, it can generate both acidic anode water and basic cathode water, The electrolyzed water can be used as a neutralizing agent for adjusting the pH of the oxidizing agent and neutralizing the contents of the treatment tank or the crushing tank. In addition, when electrolyzed water is produced, when the cathode water remains, it can be temporarily retained and used for neutralization of the contents.

  Moreover, it is preferable to perform neutralization by the said neutralization means of the accommodation, using the pH measurement means arrange | positioned in a processing tank, measuring the pH of the accommodation. The pH measuring means can be used without particular limitation as long as it can measure pH. An example of such pH measuring means is a pH sensor.

  For example, when the container after crushing flows into the sewer, the pH of the container is adjusted to pH 5.6 to 8.6, which is an inflow standard to the sewer, using neutralization means and pH measurement means. It is preferable.

  Moreover, it is preferable to discharge | emit the accommodation after crushing outside from a processing tank or a crushing tank through a discharge port, after the temperature falls below predetermined temperature. Therefore, for example, it is preferable to measure the temperature of the contents using temperature measuring means and confirm that the temperature has dropped below a predetermined temperature. In this case, the temperature measuring means is preferably arranged in the processing tank or in the crushing tank when a crushing tank is provided. The temperature measuring means can be the same as described above.

  The temperature standard for inflow water to the sewer is less than 45 ° C. For this reason, it is preferable to discharge | release the accommodation to a sewer, after confirming with the temperature measurement means that the temperature of the accommodation after crushing became less than 45 degreeC.

  As described above, since the temperature of the container is less than 45 ° C. when discharged into the sewer, for example, a pipe made of a hard polyvinyl chloride resin or chloride used as a pipe around the bath from the outlet to the sewer Vinyl resin lined steel pipes can be used. Thereby, the garbage processing apparatus of this invention can be comprised at low cost.

  In addition, you may reduce the temperature of the accommodation after crushing by performing natural cooling for predetermined time. Or you may forcibly cool the accommodation after crushing using cooling means, such as a cooling fan, a heat pump, and a Peltier device, for example.

  Moreover, when the garbage processing apparatus of this invention is equipped with the electrolyzed water production | generation part using a diaphragm, it supplies a cathode water to the processing tank or crushing tank after discharging | emitting a contained material, a processing tank or a crushing tank is used. You may wash. By performing this tank cleaning step, it is possible to suppress the generation of odor, slime, etc. due to the remaining contents.

  The crushed container may be further subjected to biological treatment. At this time, it is preferable that the accommodation is adjusted to pH and temperature and transferred to, for example, a biological treatment tank. Thus, by adjusting the pH and temperature of the container after crushing, for example, microorganisms in the biological treatment tank can be prevented from being killed. In this case as well, the above-described neutralization means and cooling means can be used.

  The crushed container can also be used for liquid fertilizer. Also in this case, it is preferable to adjust the pH and temperature of the crushed container as in the case of performing biological treatment.

  When the crushed container is used for biological treatment, or when the crushed container is used as liquid fertilizer, the crushed container is brought into contact with a reducing agent such as activated carbon to leave the remaining unreacted material. It is particularly preferred to remove the oxidant.

Next, a garbage disposal method using the garbage disposal apparatus of the present invention will be described.
First, the garbage is softened by being heated together with the oxidant by the heating means in the treatment tank. Next, the heated garbage is crushed by crushing means. Here, softening means that the hardness, tensile strength, bending strength, etc. of the garbage is reduced, and the molecular weight of the insoluble organic matter constituting the garbage is lowered, resulting in a swollen state in water.

  By heating the garbage with an oxidizer, hydrophilic functional groups such as carbonyl groups, carboxyl groups, and hydroxyl groups are introduced into the organic matter that constitutes the garbage. As a result, the affinity of garbage for water is increased. Improves. Here, even garbage containing high molecular weight hydrophobic organic substances is easily hydrolyzed by heating in a state where the affinity for water is improved by the oxidizing action of the oxidizing agent. It becomes like this. By such a hydrolysis reaction, the garbage is reduced in molecular weight, and some components are dissolved in water or become a gel to reduce the particle size.

  By improving the affinity of garbage for water and reducing the particle size, the solid-liquid separation property of the mixture of garbage and water is lowered, and the state where the garbage is dispersed in water is stabilized. In other words, the garbage after heating is less likely to settle or deposit on the bottom of the apparatus than the garbage before heating. However, since garbage with a large particle size tends to settle, the garbage with such a large particle size is crushed by a crushing means.

  Thus, after heating and softening garbage with an oxidizing agent, crushing the garbage after heating facilitates the crushing process and further reducing the particle size of the garbage by crushing. Can do.

  As described above, the garbage processing apparatus of the present invention is characterized in that the garbage and the oxidizing agent are heated and softened, and then the heated garbage is crushed. This makes it possible to divide the number of injections into multiple parts, such as large lumps and cores of vegetables, or fibrous vegetables, which are difficult to crush with conventional disposers, or without being divided before the introduction. Can be processed.

Moreover, after roughly crushing raw garbage, you may use the raw garbage after the rough crushing for the said heating process and crushing process. In this method, since the garbage is first roughly crushed and reduced in size, the oxidation when heated with the oxidizing agent is facilitated. Therefore, the garbage can be softened (liquefied or reduced in molecular weight) within a short time.
Moreover, you may perform simultaneously the process and the crushing process of heating garbage with an oxidizing agent.

In addition, it is preferable that heating temperature shall be 50 degreeC or more and 150 degrees C or less as mentioned above.
Moreover, it is preferable that pH of an oxidizing agent is 3 or more and 6.5 or less, and it is preferable that the effective chlorine concentration of an oxidizing agent is 50-3000 ppm.
In particular, when the garbage is heated at a low temperature (especially 50 ° C. or more and less than 100 ° C.), it is preferable to use an oxidizing agent having an effective chlorine concentration of 500 ppm or more and a pH of 3 or more and 6.5 or less. In this case, the weight ratio of the garbage is preferably 60% or less.
Note that the heating time is appropriately changed depending on the type of oxidizing substance contained in the oxidizing agent, the effective chlorine concentration of the oxidizing agent, and the like.

  As described above, the use of the garbage processing apparatus of the present invention increases the affinity of garbage for water, increases the solubility of garbage in water, and stabilizes the dispersion of garbage in water. Increases nature. For this reason, even when discharging garbage using water as a medium, it is possible to make it difficult to cause sedimentation and accumulation of the garbage in the piping and the resulting blockage of the piping.

Hereinafter, the present invention will be specifically described with reference to the drawings.
(Embodiment 1)

A discharge port is provided at the bottom of the treatment tank 3. In the present embodiment, the discharge port and the external drain pipe 8 are connected by an external discharge valve 9. The external discharge valve 9 is pressure-resistant and has a role of sealing so that gas generated when the garbage and the oxidant are heated does not leak to the outside of the treatment tank 3.
In addition, as a structure of the discharge port of the processing tank 3, the fixed amount of water was stored in the external drain pipe 8 in the processing tank 3 in addition to the structure as shown in FIG. It may be configured to have a mechanism for discharging water. The same applies to the following embodiments.

  Moreover, in the garbage processing apparatus 1 of FIG. 1, the insertion port 7 of the processing tank 3 is attached so that it may be located in the sink drain port of the sink surface 10, for example.

  Next, the operation method of the garbage disposal apparatus 1 will be described below in order.

  First, the external discharge valve 9 is closed, and garbage is introduced into the treatment tank 3 from the introduction port 7. Thereafter, the oxidant 2 is introduced into the treatment tank 3 from the oxidant supply means 4, and the garbage and the oxidant 2 are brought into contact with each other. The oxidant supply means 4 includes a valve 11, and the oxidant 2 is supplied to the treatment tank 3 by opening and closing the valve 11.

The oxidant supply means 4 can be set to automatically supply the oxidant 2 for each processing of garbage, for example. Thereby, the user can save the trouble of supplying the oxidant 2 to the treatment tank 3 for each treatment.
Further, by increasing the capacity of the oxidant supply means 4, it is possible to reduce the frequency with which the user prepares the oxidant 2. In addition, you may throw in the oxidizing agent 2 before garbage. Further, the amount of the oxidant to be added is appropriately changed according to the amount of garbage. The same applies to the following embodiments.

Subsequently, the inlet 7 is closed with a lid. Next, the contents in the treatment tank are heated by the heating means 5. At this time, the temperature of the garbage stored in the processing tank 3 is measured by the temperature measuring means 13 provided in the processing tank 3. The heating means 5 is controlled by a heating control means (not shown) built in the electrical component 12, and the heating temperature is maintained at a predetermined temperature.
In the case where the opening / closing detection means (not shown) is provided to indicate that the lid has been closed, the opening / closing detection means detects that the lid has been closed, and then uses the information from the opening / closing detection means to detect the electrical component 12. A heating control means (not shown) incorporated in the control unit 5 may control the heating means 5.

  After heating for a predetermined time, the heating means 5 is stopped and the heating is terminated. Subsequently, the rotating blade 6 installed in the inside of the processing tank 3 is rotated by the motor 14, and the softened garbage is crushed. In the present embodiment, the motor 14 is also controlled by the electrical component 12. The same applies to the following embodiments.

  After a predetermined time has elapsed, or after the rotational speed or the rotational speed of the rotary blade 6 has reached a predetermined value, the rotary blade 6 is stopped and the crushing of garbage is ended. After the temperature of the crushed garbage is sufficiently lowered, the external discharge valve 9 is opened, and then discharged through the external drain pipe 8 together with the oxidizer 2 to the outside such as a sewer. At this time, it is preferable to open the lid that closes the charging port 7 so that the contents in the processing tank 3 are communicated with each other so that the contents in the processing tank are easily discharged.

  In addition, in this embodiment, the crushing of the garbage with the rotary blade 6 is performed after completion | finish of the softening by heating. After roughly crushing garbage, the roughly crushed garbage may be subjected to a heating step and a crushing step. Alternatively, the garbage may be crushed by simultaneously rotating the rotary blade 6 while heating the garbage.

(Embodiment 2)
FIG. 2 shows a garbage disposal apparatus according to another embodiment of the present invention. In FIG. 2, the same components as those in FIG. The same applies to the following embodiments.

  The garbage processing apparatus 20 in FIG. 2 further includes a crushing tank 21 connected to the processing tank 3 and a discharge valve 22 disposed between the processing tank 3 and the crushing tank 21. In the present embodiment, the rotary blade 6 that is a crushing means is installed in the crushing tank 21.

  In the present embodiment, the treatment of garbage can be basically performed in the same manner as in the first embodiment.

  First, the discharge valve 22 is closed, and garbage is introduced into the treatment tank 3 from the introduction port 7. Thereafter, the oxidant 2 is introduced into the treatment tank 3 from the oxidant supply means 4, and the garbage and the oxidant 2 are brought into contact with each other.

  Subsequently, the inlet 7 is closed with a lid. When an opening / closing detection means (not shown) is provided, a heating control means (not shown) built in the electrical component 12 operates the heating means 5 based on information from the opening / closing detection means after detecting the opening / closing. Let

  The garbage put into the treatment tank 3 is heated at a predetermined temperature by the heating means 5 together with the oxidizer 2 and is softened. The temperature of the contents stored in the processing tank 3 is measured by the temperature measuring means 13 and is maintained at a predetermined temperature by a heating control means (not shown) built in the electrical component 12.

After the garbage is heated for a predetermined time, the heating means 5 is stopped. Next, the discharge valve 22 is opened, and the heated contents are discharged from the treatment tank 3 to the crushing tank 21. At this time, it is preferable to open the lid that closes the charging port 7 so as to allow the outside and the inside of the treatment tank 3 to communicate so that the heated contents are easily discharged.
The discharge valve 22 may be opened manually. Alternatively, the heating control means (not shown) and the discharge valve 22 may be interlocked so that the discharge valve 22 is automatically opened after the heating of the garbage is completed.

  Then, the softened garbage is crushed by rotating the rotary blade 6 inside the crushing tank 21 with the motor 14. After the temperature of the crushed garbage is sufficiently lowered, the external discharge valve 9 is opened, and then discharged through the external drain pipe 8 together with the oxidizer 2 to the outside such as a sewer.

In addition, the garbage remaining without being discharged into the crushing tank 21 may be led to the crushing tank 21 by flowing tap water into the sink and discharged together with the tap water, or taken out and discarded as a solid matter. May be. Alternatively, the remaining garbage may be left as it is and processed together with other garbage.
When the remaining garbage is further processed with other garbage, it is preferable to take it out and dispose of it separately if the garbage does not reduce to some extent.
These are the same in the first embodiment and the third embodiment.

Moreover, it is preferable to provide a classification means in the processing tank 3 or the crushing tank 21 so that the garbage that has not been sufficiently crushed moves toward the discharge port and does not clog the discharge port and the drain pipe. In the garbage processing apparatus of FIG. 2, classification means 23 is provided in the lower part of the processing tank 3.
Thus, by providing the classification means 23, it becomes possible to prevent the garbage which has not been crushed from moving toward the discharge port.

(Embodiment 3)
FIG. 3 shows a garbage disposal apparatus according to still another embodiment of the present invention. In FIG. 3, the same components as those in FIG.
In the garbage disposal apparatus 30 of FIG. 3, the oxidant supply means 4 includes an electrolyzed water generating unit 31 that generates electrolyzed water containing an oxidizing substance.

The electrolyzed water generating unit 31 includes an electrolyzer 32, an anode 33 and a cathode 34 disposed in the electrolyzer 32, an energizer 35 for energizing between the anode 33 and the cathode 34, and between the anode 33 and the cathode 34. The diaphragm 36 is provided.
In the present embodiment, electrolyzed water containing an oxidizing substance, which is generated by the electrolyzed water generating unit 31, is used as the oxidant 2.

  Moreover, the garbage processing apparatus 30 of FIG. 3 is provided with the tank 37 which stores the electrolyzed water produced | generated in the electrolyzed water production | generation part 31. As shown in FIG.

  In addition, also in the garbage processing apparatus 1 of FIG. 1 and the garbage processing apparatus 20 of FIG. 2, you may install the oxidizing agent supply means 4 provided with the electrolyzed water production | generation part 31 as shown in FIG.

  Also in the garbage processing apparatus 30 of FIG. 3, the rotary blade 6 which is a crushing means is installed in the processing tank 3 similarly to FIG. In the garbage processing apparatus of FIG. 3, as shown in FIG. 2, a crushing tank may be installed separately from the processing tank, and a rotary blade may be installed inside the crushing tank.

Also in the present embodiment, the treatment of garbage can be basically performed in the same manner as in the first embodiment.
First, the external discharge valve 9 is closed, and garbage is introduced into the treatment tank 3 from the introduction port 7. Then, the electrolyzed water containing the oxidizing substance generated in the electrolyzed water generating unit 31 is supplied as the oxidant 2 into the treatment tank 3 from the oxidant supply means 4 via the valve 11, and the oxidant and garbage Contact.

  In order to determine the supply amount of electrolyzed water to the garbage, the garbage processing apparatus 30 of FIG. 3 further includes a weight measuring means 38 for measuring the weight of the treatment tank 3. By linking the weight measuring means 38 with the valve 11 of the oxidant supply means 4, it is possible to supply an amount of electrolyzed water necessary for softening garbage. Thereby, it becomes possible to operate the garbage processing apparatus 30 efficiently. In addition, in order to determine the supply amount of oxidizing agents other than electrolyzed water, the weight measuring means 38 may be used.

  Subsequently, the inlet 7 is closed with a lid. When an opening / closing detection means (not shown) is provided, a heating control means (not shown) built in the electrical component 12 operates the heating means 5 based on information from the opening / closing detection means after detecting the opening / closing. Let

  Garbage thrown into the treatment tank 3 is heated and softened together with the electrolyzed water at a predetermined temperature by the heating means 5. At this time, the temperature of the contents in the processing tank 3 is measured by the temperature measuring means 13. Further, the temperature of the stored item is maintained at a predetermined temperature by a heating control means (not shown) built in the electrical component 12.

After heating for a predetermined time, the heating means 5 is stopped, and the rotating blade 6 inside the treatment tank 3 is rotated by the motor 14, whereby the softened garbage is crushed.
After a predetermined time has elapsed, or after the rotational speed or the rotational speed of the rotary blade 6 has reached a predetermined value, the rotary blade 6 is stopped and the crushing of garbage is ended.

  After the crushed garbage is sufficiently cooled, the external discharge valve 9 is opened, and then discharged together with the oxidized water through the external drain pipe 8 to the outside such as a sewer. At this time, it is preferable to open the lid that closes the charging port 7 so that the contents in the processing tank 3 are communicated with each other so that the contents in the processing tank are easily discharged.

  In the present embodiment, electrolyzed water containing an oxidizing substance is generated from the electrolyzed water generating unit 31, and the electrolyzed water is used as an oxidizing agent. Since electrolyzed water containing an oxidizing substance can be generated simply by electrolyzing water in which an electrolyte such as a halogen salt is dissolved, management of the oxidant supply means is facilitated. Therefore, it is possible to install the garbage disposal apparatus of the present invention not only in industrial applications but also in places where management of chemical substances is difficult, such as general households and restaurants.

As the electrolyzed water, it is preferable to use acidic anodic water generated in the electrolyzed water generating unit 31. Further, basic cathode water is retained in the tank 37, and after crushing, the cathodic water is supplied from the tank 37 to the contents of the treatment tank 3, so that the crushed contents are contained in the treatment tank 3. It becomes possible to sum. In this case, the tank 37 and the valve 11 for accommodating the cathode water function as pH control means. Moreover, you may wash | clean the inside of the processing tank 3 after discharging the accommodation using the cathode water.
The produced anode water and cathode water may be mixed so as to have a predetermined pH, and the mixture may be used as an oxidizing agent.

  Furthermore, another pH control means may be provided to adjust the pH of the electrolyzed water in the electrolyzed water generation unit. At this time, the water to be electrolyzed may be electrolyzed while being measured by a pH measuring means such as a pH sensor.

  In Embodiments 1 to 3, the crushed container may be discharged into sewage after adjusting the pH and temperature. Or the accommodation thing after crushing which adjusted pH and temperature may be processed in a biodegradation tank, and you may discharge | release to sewage after that.

  The present invention will be described based on the following examples. In addition, the following examples do not limit the present invention.

Example 1
The garbage was processed using the garbage processing apparatus shown in FIG.
The lid for closing the treatment tank 3 and the inlet 7 was made of SUS304. The internal volume of the processing tank 3 was 300 ml. A band heater was used as the heating means 5. At this time, a thermocouple was put into the treatment tank 3 so as to come into contact with the stored item, the temperature of the stored item was measured using a thermocouple, and the temperature of the stored item was controlled by the heating control means.

  As the oxidant supply means 4 having the electrolyzed water generating unit 31, an ion cleaning water manufacturer (MS-W1 manufactured by Matsushita Electric Industrial Co., Ltd.) was used. The tap water to which salt was added was electrolyzed using an ion washing water maker, and electrolyzed water (pH 2.5, effective chlorine concentration: 1500 ppm) on the anode side was used as an oxidizing agent.

  As the motor 14 and the rotary blade 6 serving as the crushing means, the motor and cutter blade of the cooking mill AVA14-1215 of the National Fiber Mixer MX-X62 were used.

  At room temperature, 50 g of standard garbage (water content: about 80%) as shown below was charged into the treatment tank 3, 75 ml of the oxidizing agent was charged, and the charging port 7 was closed with a lid.

  Breakdown of standard garbage is cabbage 12.5g, potato 2.5g, onion 2.5g, radish 2.5g, apple 7.5g, orange 7.5g, raw meat 1.5g, raw fish 4.0g, chicken eggshell 1g , 5.5 g of rice, and 3.0 g of tea husk, for a total of 50 g. This composition is a composition that is regarded as standard garbage by the Japan Electrical Manufacturers' Association.

The standard garbage was heated at 150 ° C. for 1 hour and softened. At this time, the weight ratio of garbage was 40%. Here, the weight ratio of the garbage refers to the ratio of the garbage in the total weight of the oxidizing agent and the garbage. In addition, the weight ratio of garbage can be calculated on the assumption that the specific gravity of electrolyzed water is 1.
Then, it cooled to room temperature, the cutter blade was rotated for 1 minute, and the garbage was crushed. After crushing, the external drain valve was opened, and the garbage after crushing was discharged together with the oxidizing agent.

Next, the particle size distribution of the effluent was measured. For the measurement of particle size distribution, 4750, 2000, 1000, 850, 425, 250, 106, and 75 micron standard sieves and a micro-type electromagnetic vibration sieve (M-2 type, Tsutsui Rikenki Co., Ltd.) were used. . After vibrating for 10 minutes with the vibration adjustment dial 6 of the electromagnetic vibration sieve, the weight of each particle size component was measured. In addition, since the particle size distribution after 20-minute vibration is almost the same, the vibration time was set to 10 minutes in the following examples.
<< Comparative Example 1 >>

Example 1 except that oxidant was not supplied and heated (that is, the food was not softened), 75 ml of tap water was added to the food, the cutter blade was rotated for 1 minute, and the food was crushed. Garbage was treated in the same way. The same amount of the same weight as that of Example 1 was used for the garbage to be added.
The particle size distribution of the discharged liquid was measured in the same manner as in Example 1.

The particle size distribution of the garbage contained in the effluent of Example 1 and Comparative Example 1 is shown in FIG. 4, and the cumulative particle size distribution is shown in FIG.
As a result, it can be seen that the garbage in Example 1 is smaller than that in Comparative Example 1.

  In addition, 5 ml of the effluent discharged in Example 1 and Comparative Example 1 was diluted 3 times, placed in a 20 ml test tube and allowed to stand, and the amount of solid content was observed every predetermined time. FIG. 6 shows a graph in which the vertical axis represents the ratio of the height of the precipitated solid content to the initial height as a percentage value, and the horizontal axis represents time. Here, the initial height refers to the height from the bottom of the test tube to the solid-liquid interface at that time (solid) (Height height).

  As a result, the garbage (Comparative Example 1) subjected to only the crushing treatment settled down to half the height in about 50 minutes. On the other hand, in the garbage (Example 1) which was crushed after softening, the solid content hardly settled even after 200 minutes. Even after 5 days had passed, the sedimentation height of the garbage after the treatment retained 96% of the initial height, and the garbage after the treatment settled only about 4%.

  As mentioned above, in the disposer which performs only the conventional crushing, the particle size of garbage is large, and garbage settles in about 1 hour after processing. For this reason, the garbage after a process settles and deposits in a processing tank, piping, a pipe tub, etc., and the fluidity | liquidity falls. Furthermore, there is a possibility that the piping may be blocked by the garbage after the treatment.

On the other hand, the garbage which was crushed after being heated with the oxidizing agent as in the present invention hardly settled even after about 5 days. Therefore, the garbage processed by the garbage processing apparatus of this invention is very convenient for discharge | emission, transfer, etc. which use a liquid as a medium.
Example 2

In this example, a corn core was treated in the same manner as in Example 1 using the same apparatus as in Example 1 except that corn core was used instead of standard garbage. Specifically, a cylindrical corn core (25 g) having a diameter of 30 mm and a height of 20 mm was placed in the treatment tank 3, and then 75 ml of the same oxidizing agent used in Example 1 was added. Here, the weight ratio of raw garbage (corn core) was 25%.
After heating this corn core together with an oxidizing agent to 150 ° C. for 1 hour, the cutter blade was rotated for 1 minute to crush it. The container containing the treated corn core was discharged by opening the drain valve. The particle size distribution of the discharged liquid was measured in the same manner as in Example 1.
<< Comparative Example 2 >>

Softening was not performed, and the corn core was treated in the same manner as in Example 2 except that 75 ml of tap water was added to the corn core and crushed. The same corn core as in Example 2 was used.
The particle size distribution of the discharged liquid was measured in the same manner as in Example 1. After the treatment, two spherical objects having a diameter of 20 mm remained in the treatment tank 3.

  FIG. 7 shows the cumulative particle size distribution of the particles contained in the effluents of Example 2 and Comparative Example 2. As shown in FIG. 7, it can be seen that in Example 2, the corn core is made smaller than Comparative Example 2.

  In Comparative Example 2, a lump of corn remained only by crushing the corn core. On the other hand, in Example 2, a large lump was not recognized, and the corn core made into small particles was well dispersed in water.

Furthermore, the hardness of the corn core was measured using a rubber hardness meter before and after the softening treatment. As a result, before the softening treatment, the hardness of the corn core was 20 to 38, and was 82 at a hard place. On the other hand, after the softening treatment, the hardness of the corn core was 0, which was not measurable. Thus, by softening the garbage, the subsequent crushing becomes easy, and the garbage becomes smaller particles as compared with the processing only by crushing. For this reason, the treated garbage is well dispersed in water, and the state is stabilized. Therefore, by using the garbage processing apparatus of the present invention, it is possible to easily treat even a hard material such as a corn core, which has conventionally been difficult to crush.
Example 3

The treatment was performed by the same apparatus and the same method as in Example 1 except that 35 g of onion skin was used instead of standard garbage. Here, the weight ratio of raw garbage (onion skin) was 32%. The particle size distribution of the particles contained in the effluent was measured in the same manner as in Example 1.
<< Comparative Example 3 >>

  The treatment was performed by the same apparatus and the same method as in Example 1 except that 75 ml of tap water was added to 35 g of onion skin and only the crushing treatment was performed. The particle size distribution of the particles contained in the effluent was measured in the same manner as in Example 1.

FIG. 8 shows the cumulative particle size distribution of the particles contained in the effluent of Example 3 and Comparative Example 3. As shown in FIG. 8, it can be seen that the onion skin is made smaller in Example 3 than in Comparative Example 3. It is known that the onion skin is difficult to be reduced by crushing alone, but its particle size is as small as that of standard garbage. Therefore, by using the garbage processing apparatus of the present invention, it is possible to disperse the onion skin in the discharged liquid.
Example 4

It processed using the apparatus and method similar to Example 1 except having used the watermelon skin instead of standard garbage. Here, the shape of the watermelon skin was approximately 20 mm × 100 mm × height 30 mm, and its weight was 32 g. Here, the weight ratio of garbage (watermelon skin) was 30%.
The particle size distribution of the particles contained in the effluent was measured in the same manner as in Example 1.
<< Comparative Example 4 >>

Using the same apparatus as in Example 1, 75 ml of tap water was added to the skin of watermelon, and the treatment was performed in the same manner as in Example 1 except that only crushing treatment was performed. Here, the watermelon skin weight was 32 g, the same as in Example 4. However, since the watermelon skin size was difficult to crush, the watermelon skin size was 20 mm × 20 mm × 30 mm. Cut.
After the crushing treatment, the particle size distribution of the particles contained in the effluent was measured in the same manner as in Example 1.
In addition, after the crushing process, two spherical objects having a diameter of 20 mm remained in the processing tank 3.

  FIG. 9 shows the cumulative particle size distribution of the particles contained in the effluent of Example 4 and Comparative Example 4. As shown in FIG. 9, it can be seen that the watermelon skin is smaller in Example 4 than in Comparative Example 4. Moreover, in the comparative example 4, the lump thing remained only by the crushing process. On the other hand, in Example 4, a large lump was not recognized, and the skin of watermelon made into small particles was well dispersed in the discharged liquid.

Moreover, the hardness of the watermelon skin was measured before and after the softening treatment using a rubber hardness meter. Before the softening treatment, the watermelon skin had a hardness of about 15, and the hardness of the outer skin was 58. After the softening treatment, the watermelon skin hardness was 0, which was not measurable. Thus, by softening, the subsequent crushing process becomes easy, and it becomes a particle | grain with smaller garbage compared with the process only of crushing. For this reason, the treated garbage is well dispersed without being settled easily in water, and the state is stabilized. Therefore, by using the garbage processing apparatus of the present invention, it is possible to easily treat even a hard thing such as a watermelon skin, which has conventionally been difficult to crush.
<< Examples 5 to 8 >>

A watermelon skin was treated in the same manner as in Example 4 except that the temperature and time of the softening treatment were changed as follows. The watermelon skin was the same as in Example 4.
In Example 5, it processed at 100 degreeC for 1 hour. In Example 6, it processed at 80 degreeC for 1 hour. In Example 7, it processed at 50 degreeC for 1 hour. In Example 8, it processed at 26 degreeC for 15 hours.
The particle size distribution of the particles contained in the effluent in Examples 5 to 8 was measured in the same manner as in Example 1.

Of the particle size distributions of the particles contained in the effluents of Examples 4 to 8, the cumulative particle size distribution in Example 4, Example 6 and Example 8, and the cumulative particle size distribution in Comparative Example 4 as a comparison are shown in FIG. 10 shows. As shown in FIG. 10, in Examples 4, 6 and 8, the watermelon skin is made smaller than Comparative Example 4.
In addition, as the temperature of the softening treatment decreases (Example 4: 150 ° C., Example 6: 80 ° C., Example 8: 26 ° C.), even if the treatment time is increased, the watermelon skin is made smaller. The effect was small.

  Next, 5 ml each of the effluents of Examples 4 to 8 and the effluent of Comparative Example 4 were diluted three-fold, placed in a 20 ml test tube, allowed to stand, and the amount of solid content settled every predetermined time. Observed. Table 1 shows values obtained by expressing the ratio of the height of the solid content after 100 hours from the initial height as a percentage value.

As shown in Table 1, when the heating temperature is 150 ° C. or less, the higher the heating temperature, the larger the settling height after 100 hours with respect to the initial height, and the dispersion stability of the garbage after the treatment is Improved.
<< Examples 9 to 13 >>

Garbage was processed using the same garbage processing apparatus as in Example 1.
As the oxidized water, the electrolyzed water (pH 5.0, effective chlorine concentration: 1500 ppm) was used by mixing the electrolyzed water on the anode side and the cathodic water on the cathode side.

  At room temperature, 50 g of the following standard garbage (water content: about 80%) was charged into the treatment tank, and then 75 ml of the oxidized water was charged to close the charging port.

  Breakdown of standard garbage is carrot 9g, cabbage 9g, banana 5g, apple 5g, grapefruit skin 5g, bird peach bone (boiled) 5g, eggshell 1g, cooked rice 5g, tea shell 2g, total 50g there were. This composition is a composition which is regarded as standard garbage in the “Disposer Wastewater Treatment System Performance Standard (Draft)” (Japan Sewerage Association).

The standard garbage was softened by heating at 50 ° C. for 3 hours. At this time, the weight ratio of garbage was 40%.
Then, it cooled to room temperature, the cutter blade which is a crushing means was rotated for 1 minute, and the garbage was crushed. After this crushing, the drain valve was opened, and the garbage after crushing was discharged together with the oxidizing agent.

  Further, 5 ml of the discharged effluent was diluted 3 times, placed in a 20 ml test tube and allowed to stand, and the sedimentation height after 100 hours was recorded. The ratio of the height of the precipitated solid content to the initial height was calculated as a percentage value, and the dispersion stability of the treatment liquid was evaluated.

Garbage was treated in the same manner as in Example 9 except that the pH of the oxidizing agent was changed as follows.
In Example 10, it processed using the electrolysis water of pH2.5. In Example 11, the treatment was performed using pH 3 electrolyzed water. In Example 12, it processed using the electrolyzed water of pH 6.5. In Example 13, it processed using the electrolyzed water of pH7.

  Moreover, the ratio of the height of the settled solid content to the initial height 100 hours after standing in the effluents of Examples 10 to 13 (solid content sedimentation height / initial height) Measurement was performed in the same manner as in Example 9. The results are shown in Table 2.

As a result, as shown in Table 2, in Example 10 in which the pH of the oxidizing agent was 2.5 and Example 13 in which the pH was 7, the treated garbage settled to almost half after 100 hours. did. On the other hand, in Example 9 in which the pH of the oxidizing agent is 5, Example 11 in which the pH is 3, and Example 12 in which the pH is 6.5, the settling height of the garbage after the treatment is initially More than 70% of the height was retained, and the garbage after treatment had settled only about 30%. Therefore, the dispersion stability of the garbage after a process can be made high by using the oxidizing agent adjusted to pH 3 or more and 6.5 or less.
<< Examples 14 to 17 >>

Garbage was treated in the same manner as in Example 9 except that the heating temperature was changed as follows. The same garbage as in Example 9 was used.
In Example 14, it heated at 100 degreeC. In Example 15, it heated at 90 degreeC. In Example 16, it heated at 40 degreeC. In Example 17, it heated at 25 degreeC.
Moreover, the ratio of the height of the settled solid content to the initial height 100 hours after standing in the effluents of Examples 14 to 17 (solid content sedimentation height / initial height) Measurement was performed in the same manner as in Example 9. The results are shown in Table 3. Table 3 also shows the results of Example 9.

In Example 14 heated at 100 ° C. and Example 17 heated at 25 ° C., the treated garbage settled to nearly half after 100 hours. On the other hand, in Example 15 heated at 90 ° C. and Example 9 heated at 50 ° C., the sedimentation height of the garbage after the treatment retained about 80% of the initial height, and the garbage was 20%. It only settled to a certain extent. Therefore, by using an oxidizing agent having an effective chlorine concentration of 1500 ppm and a pH of 5, and heating the garbage together with the oxidizing agent to 50 ° C. or more and less than 100 ° C., the dispersion stability of the treated garbage is increased. can do.
<< Examples 18 to 19 >>

The garbage was treated in the same manner as in Example 9 except that the weight ratio of the garbage was changed as follows. The same garbage as in Example 9 was used.
In Example 18, the weight ratio of garbage was 60%. In Example 19, the weight ratio of garbage was 80%.
In the effluents of Examples 18 to 19, the ratio of the height of the precipitated solid content to the initial height after 100 hours from standing (the sedimentation height of the solid content / initial height) is The measurement was performed in the same manner. The results are shown in Table 4. Table 4 also shows the results of Example 9.

As shown in Table 4, in Example 19 in which the weight ratio of the garbage was 80%, the treated garbage settled down to almost half after 100 hours. On the other hand, in Example 18 in which the weight ratio of the garbage is 60% and in Example 9 in which the weight ratio of the garbage is 40%, the settling height of the treated garbage is 70% or more of the initial height. The waste after treatment was settled only about 30%. Therefore, when heating garbage with an oxidizing agent, it is preferable to adjust the amount of oxidized water so that the weight ratio of garbage becomes 60% or less.
<< Examples 20 to 21 >>

Garbage was treated in the same manner as in Example 9 except that the effective chlorine concentration of the oxidizing agent was changed as follows. The same garbage as in Example 9 was used.
In Example 20, the effective chlorine concentration of the oxidizing agent was 400 ppm. In Example 21, the effective chlorine concentration of the oxidizing agent was 500 ppm.

  Moreover, the ratio of the height of the settled solid content to the initial height 100 hours after standing in the effluents of Examples 20 to 21 (solid content sedimentation height / initial height) Measurement was performed in the same manner as in Example 9. The results are shown in Table 5. Table 5 also shows the results of Example 9.

  As shown in Table 5, in Example 20 in which the effective chlorine concentration of the oxidizing agent was 400 ppm, the treated garbage settled down to almost half after 100 hours. On the other hand, in Example 21 in which the effective chlorine concentration of the oxidizing agent is 500 ppm and in Example 9 in which the effective chlorine concentration is 1500 ppm, the settling height of the garbage after the treatment is maintained at 70% or more of the initial height. However, only about 30% of the garbage after treatment had settled. Therefore, when heating at 50 ° C. using a pH 5 oxidizing agent, the effective chlorine concentration of the oxidizing agent is preferably 500 ppm or more.

  As described above, in the conventional disposer that performs only the crushing process, the particle size of the treated garbage is large and the sedimentation is fast. For this reason, for example, it settles and deposits in a processing tank, piping, or a pipe trough, and the fluidity falls. Furthermore, piping and the like may be blocked. On the other hand, by processing using the garbage processing apparatus of the present invention, even after 100 hours have elapsed after processing, the processed garbage hardly settles. For this reason, it becomes very convenient when the garbage after processing is discharged or transferred using water as a medium.

  The garbage processing apparatus of the present invention is useful as an apparatus for crushing and discharging garbage, and for example, is also useful as an apparatus for transferring solid organic matter using water as a dispersion medium. Therefore, the garbage processing apparatus of the present invention can be used for disposal of waste by dispersing organic solid waste generated in a factory or the like in an aqueous dispersion medium. Thereby, for example, it becomes possible to unify the processing of waste.
